PATENT ALEXANDER GOVAN, OF GLASGOW, SCOTLAND.

BRAKE FQRAUTOCARS.

SPECIFICATION-forming part of` Letters Patent No. 732,846, dated July 7, 1903., Application filed December 9, 1902. Serial No. 134,491. (No model.)

'To all whom it may concern.-

Beit known that I, ALEXANDER GovAN, a subject of the King of the United Kingdom of Great Britain and Ireland, residing at 47 "Hozier street, Bridgeton, Glasgow,` Scotland,

have invented certain new andluseful Improvements in Brakes for Autocars and other Vehicles, (for which` application for patent p has been made in Great Britain, No. 12,824,

dated June 5, 1902,) of which the following is a specification.

This invention relates to brakes for autol cars and other vehicles in which a brake band or block is applied to a Wheel or drum at each side ofthe axle; and it has for itsobject to provide simple and efficient means for equally distributing the brake-pressure on the two v wheels.

The invention is illustrated by the accompanying drawings, in Which!- Figure 1 is a side elevation, and Fig. 2 a plan, of part of the framingand axle of a motor-car, showing one modification of the improved brake-equalizing gear. j

In the drawings, A represents the framing of the car, and B the axle carrying the ru nl ning-wheels C, and D the brake ,wheels or drums.

The brakes employed are preferably of the band type and applied each by a lever-arm,

` to which may be jointed the ends of the band H, Whose opposite end is attached to one arm I of a bell-crank I. The brake-bands E on each side of the vehicle are thus connected to `bell-cranks I, whose inner arms l2 are connected together by a rod or link J. The bellcranks I are each mounted on brackets K, secured on the brake-lever handle L or on an upright arm on the rock-shaft M, on which the brake-lever handle is secured.v The arrangement is such that on drawing over the lever-handle L, and thus partially rotating the rock-shaft M, the brackets on which the bell-cranks I are mounted have a pull applied to them, and, the inner arms I?I of the bellcranks being linked or connected together, the pull is transmitted through their outer arms I and the connecting rods or links H to the brake-lever arm G, while equality of brak'elpressureon both drums or wheels D is insured, owing to the bell-cranks I being free to turn on their centers and the whole constituting an articulated system.

Having now described myinvention, what I claim, and desire to secure by Letters Patent, is-

In brakes for autocars and like vehicles the combination With the brake-Wheels D, and brake-bands E, of stationary brackets F each securing one end of each brake-band, arms G attached to the other ends of the brake-bands,

bell-cranks I, links II jointed at one end to the arms G and at the other end connected to the outer arms I of the bell-cranks I, a rod J connecting the inner arms I? of the bellcranks I, rock-shaft M, brake-lever handles L secured to said shaft M and brackets K secured to said handles L and supporting the bell-cranks I as shown and described.

In Witness whereof I have hereunto set my hand in presence of two witnesses.
